Introduction: The Frontal Assessment Battery (FAB) is a for the assessment of executive functions. We investigated its validity and reliability and proposed normative data in a representative sample of older adults. Method: 391 healthy elderly subjects and 93 Alzheimer's disease (AD) patients performed the FAB. Internal consistency, convergent correlations, ROC curve and logistic regression were used to assess its psychometric properties. Results: We found good internal consistency, significant correlations with other tests and moderate accuracy (64%) for AD diagnosis. The use of specific subtests increased diagnostic potential (75%). Normative data stratified by age and education were proposed. Conclusion: The FAB showed adequate psychometric properties. The normative values stratified by age and education can improve its clinical use for neuropsychological assessment.

This paper analyzes the variation of Q-interrogatives in Portuguese in order to verify the effect of the use of some variables with and without cleavage in these constructions. The analysis includes real time research panel and trend analysis to investigate if the process variable is changing in the language. The results indicate that there is change at the individual level, but not in the community, provided there is progress in the formal education of the subjects. The study also aims to demonstrate how theoretical and methodological tools are applied to the field of Sociolinguistic research.
